That’s a great idea I didn’t even consider that when I was going through their different parts but yes I suppose that’s what to do for matching lengths. I would call their customer support and I’m sure they can get your the exact setup you need for a 305mm diameter.
On another note, I was just on Carvon’s website and they have the ‘Exo Commuter Add-Ons’ and one of the things it includes is a battery pack that looks professional, it’s in a custom plastic or similar material battery enclosure with a simple plug in end, so you can just slide the battery in its slot and the connection will be made without having to hook up a XT90 cable or anything. I know this is how most of the brand name Esk8 builders have their batteries designed, I was just curious if anyone knows how one would be able to create one of these ourselves. I’m sure the enclose itself is easily enough 3-D printed, but what are the electrical components, on both ends, male and female, that we would use to do this. Also, with this system, I’m sure you can have a BMS installed in there somewhere, but would you never be able to balance charge one of these? I’m guess that since in the picture provided, you can unscrew the front, and once you remove that, you just simply unplug the battery leads, and maybe they have the JST cable that’s required for cell balancing and BMS right there capable of extending to a cell balancer? Thoughts???
FYI The EXO is built/altered with a KooWheel 2 (KooBoard) Check YouTube. There’s a video out there of the disassembly of that battery.
So, are these Surf Rodz RKP trucks the best option to match the 305mm speed drive XL trucks? Do the 50 & 60mm axles actually widen the trucks by that much, or is some of that length eaten up after mounting them on the hanger? Since they’re on sale, I was thinking about buying an RKP truck set (which I assume is a pair) with 50 or 60mm axles and splitting the set & cost with one of you guys, (1 truck = ~$75 shipped total in US). Anyone have any interest in this or insight on the axle length situation? @Psychotiller?

Their is no “Best” truck. It is about how you want the truck to look and perform. Surf Rodz are good, Don’t trip trucks are good.

http://www.dtskate.com/searchresults.asp?cat=1968 This is my dream set of trucks.
Am not really a truck’s person but what would u say is the difference between the suf rodzs and the one you posted is it just the design I ordered my XL drives and haven’t decided on what front trucks to buy money is not a issue so if it’s work better I’ll buy it just don’t see the difference
The muirskate trucks guide explained trucks to me pretty well if you wanna learn.
Short cut, get precision trucks. Which company is a style choice after you start spending more than 100 dollars on 1 truck.
You might also consider Forged trucks too like the paras savants. https://www.paristruckco.com/ They are hammered out of a block of aluminum then precision cuts where necessary. I use these on my downhill board.
Still looking for 2 sets of Cavon XL. Anyone preordered that has gone a different route. Please PM me 
that’s the preorder that won’t happen till like Feb though right? Or are they actually in stock and ready to ship?
pre-orders, no V4 or XLs are readily available as of yet. Parts are still being manufactured I believe
that’s what I thought. I want to get some immediately instead of being behind in the big backlog since this preorder went up.
All xls are on backorder
V3 Speed Drive Design Flaws
Alright guys I need everyone’s opinion on a recent issue that’s been presented with the Evo/V3.
The other day my friend @STREETSURFER and I were doing some spirited riding. I own a Carvon Evo with V3 speed drives and SS (@STREETSURFER) owns v3s on his DIY build. SS and I decided to switch boards on this ride so that I could try out his new setup with venom double barrel bushings and riptide pivot cups. We were riding on a straight away at our local bike trail when SS, going full throttle for approximately a 1/2 mile at 37mph+, suddenly one motor locked up. Luckily, SS was in a full tuck at the time of the malfunction and while the board was sent into wobbles, he was able to maintain the board to a complete stop and was uninjured.
After I had realized SS was no where to be found I went back to find him. Once we flipped the board over we noticed one motor had significantly more resistance than the other. We originally thought it could be a VESC/bearing issue, because of the fact that we were riding at a high rate of speed for an extended distance. However after further inspection we found neither to be the cause of the issue.
After some self diagnostics , we believe the malfunction was caused by the motor shorting. Specifically we think that the solder joint from the windings to phase wire melted. We came to that conclusion by taking the motor sleeve/can off and also found that the magnets and windings seemed undamaged. We went to take off the sleeve off of my other working motor and realized that we couldn’t because the design flaws mentioned in kickstarter update #31:
https://www.kickstarter./projects/carvonllc/carvon-next-generation-electric-skateboards-longbo/posts/2020674
(Link was acting up, add .com in the URL to access the link)
So SS gave me his motor sleeve and it did the same thing. From there we started touching the phase wires together and comparing the resistance of each combination. We found two phase wires did not affect the resistance much when touching, which indicates the source of the issue.
I talked with Jerry and he said he would fix the Issues under warranty. I asked him if he would swap out the motor sleeve and motor fan for the updated parts so that I don’t have issues taking apart my motors in the future, but he declined. Jerry told me that I would have to pay $100 per motor for the updated parts even though he admitted that the parts he wants to put back under warranty are the cause for a major design flaw.
He said that since we have the V3 speed drives, we will have to pay to get the updated parts on the V4 speed drives. The last time I checked the only difference between the v3 and v4 speed drives was that the v3s support authentic abecs while the v4s support clones. It seems that as soon as Jerry realized the design flaws he got rid of the v3s and applied the new parts to the v4s, so that he can now say v3 owners are shit out of luck. It seems like Carvon expects customers to pay a premium price in order to do their R&D for them.
I hate to make the comparison, but when boosted released a product that had an issue ( the extended battery) they recalled them all, and fixed the issue. This divide of design between the V3 and V4 is the equivalent of boosted telling their customers that because they bought it already they need to buy the V2 extended battery to solve their issue.
The original date I received my board was September 26th, 2017 and that update which addressed the V3 design flaws was posted mid October. Jerry’s exacts words were “You know there are still backers that are waiting patiently for their boards cause they want me to fix all the kinks. But you want the board right away, so I gave it to you. Now you’re asking for the newer stuffs that’s really unfair. If whatever you read made you think there’s gonna be a better version, then you shouldn’t have ridden it and returned it back to me.”
This is especially aggravating because
- All the Evos were originally supposed to have V3’s.
- The only difference between the V3 and V3 speed drive was advertised as the ability to run abec clones.
- I didn’t opt to receive a prototype when my board was sent out sooner than other Evos.
In fact, the whole reason he sent out my board sooner was a mistake on his part. The reason he sent it to me earlier was because he mistook my order for another Danny who was order number #17, when mine was in the #70’s. And I still received the board 3-4 months past the original shipping date.
Then following that I had previously told him that I didn’t want to take the problem to forums and that I’d rather address it with him personally and as a last resort I would make the public issue. His response was “Please don’t blackmail me by saying you’re gonna do a review. Go ahead, I really don’t control what people think.”
For someone who is trying to enter the complete board market, customer service is going to be one of the huuuuuge factors that play into what makes or breaks that company. If this is the way he plans on handling customer service I don’t see much commercial hope for these products.
In conclusion I want some other viewpoints on this issue. What would you do in my shoes? I’m fairly new to the e-skate world and I’m already beginning to see some of the major issues arise. These are marketed as high performance, high speed boards, and yet when you do just that they fail. Stuck in a really shitty middle ground due to how much I love riding it, but what a nightmare working with the manufacturer has been. Thanks for any and all input!

When it comes to vendors and incidents it’s just a he said she said senerio how do we know your not lying we don’t how do we know you didn’t jump over a ledge or something and brake the wires we don’t . You have a fair point and I understand you, @Deckoz made a post about stuff like this recently I’ve delt with most venders in esk8 and let me just say this both my motors strators went bad I got no warranty or refund or anything . It’s really hard sometimes because it’s sometimes one in a million senerio or as I said a he said vs she said story. The other thing I want to adress if u say V3’s are flawed I know one man who would have proved that if it was that would be bigboytoys dude is 260 pounds and his 4wd build seems to be fine

The V3’s arent perfect but have held up 10x better than any of the hubs ive tried on the market and Ive tried most all of them save Hummies.
Ive also had to remove the can more than once due to various issues(smashed into a rock, debris, etc). Ive been able to do it everytime with some patience, not sure why he wasnt.
Ive had zero issues with shorting phase wires or broken solder joints on my motors and they get pushed hard. Any pics of the damage? Id think overheating would be the more likely cause of a motor short but that would be a shame considering the motors came temp sensor equiped and that feature has been available in the vesc tool since before the V3’s shipped.
Side note: my 4wd board got slammed into a curb at 30mph during a test drive on SPD2 and the axle bent. Jerry sent me a replacement axle and it was literally 3 screws, the axle nuts and about 20 mins of my time for replacement. I had to message him and compliment the design.

And that would be me that did that…lol
@go_electric one hell of a first post…and calling it a design flaw…holds little weight from you when @BigBoyToys has run these through the ringer…
And sounds like you are looking for something further than what hes offering since you are bringing up other issues not related to the issues with the motor.
The answer is clear. [quote=“go_electric, post:1044, topic:13119”] he would fix the Issues under warranty [/quote]
He has given you a solution to your issue. What more do you want?
I think Jerry giving you two options the two options of warranty repair or $100/motor upgrade is fair. I wouldn’t call it best in class service but I don’t think it’s totally unreasonable.
I also agree with you that given the price point and the rapidity of changes it appears less fair to early customers but companies have a lot to balance. Companies have a dilemma between innovating or freezing a design and they can be punished for both. For example, we’ve seen Elon Musk’s response when faced with backlash on updates that earlier versions Teslas didn’t receive. The irony is if v4 didn’t exist your issue would not be as pronounced.
